The makers of Hello Mummy, starring Sharaf U Dheen and Aishwarya Lekshmi in the lead, dropped the first trailer for the film a while ago. Debutant director Vaishakh Elans' film follows the adventures in the lives of Sharaf U Dheen and Aishwarya Lekshmi's characters who meet following a marriage proposal. The trailer shows Aishwarya's character Stephy telling Sharaf U Dheen's Bony that her mother does not like him. However, as it turns out, Stephy's mother is a ghost, and the trailer shows her haunting Bony with an element of humour in it.

The cast of Hello Mummy also includes Aju Varghese, Jagadish, Johny Antony, Bindhu Panicker, Adhri Joe, Sruthy Suresh, Ganga Meera, and Joemon Jyothir, among others. Bollywood actor Sunny Hinduja also stars in the film as an exorcist.

On the technical front, the film has cinematographer Praveen Kumar, music director Jakes Bejoy and editor Chaman Chakko. Jomin Mathew, Aibin Thomas, and Rahul ES produced the film under the banners of Hangover Films and A&HS Productions, with Sajin Ali, Nisar Babu and Dipen Patel serving as co-producers.

Hello Mummy is slated for a November 21 release in theatres.
